Table 4-3. Analog Input (ANI) Module
Purpose: This module is used to configure input voltage characteristics (e.g., input voltage range), and how the
input signals are interpreted (linear or square root representation).

Setting this parameter to 1 indicates the input
range is from 0 -5 volts (0 -20 mA). 0
indicates the input range is from 1 -5 volts (4 -
20 mA).

When a 0, it indicates the analog input signal
should be interpreted linearly.
When 1, it indicates the analog input signal
should be interpreted as a square root
representation of the value. When square root is
selected, input signals less than 1% (10% input
range) forces the input to its zero value.
